MACHINE FOR ATTACHING LlNlNG-HOOPS.

'srnoiFIcATIoN forming part of Letters Patent no. 645,993, dated March 27, 1900.

Application filed August 21, 1899- Serial No. 727,912. (No model.)

a citizen of the United States of America, anda resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful-Improvements in Machines for Attaching Lining-Hoops, of which the following is a specification.

My invention relates to machines for attaching lininghoops to cylindrical veneer packages. Its main objects are to suitably support the package during the process of attaching the hoops, to provide for retaining the hoops in the desired position in the package during such process, and to provide for rotating the package while the hoops are being nailed or fastened.

Other objects of difierent features of construction shown will be understood from the following description, with reference to the accompanying drawings, in which- Figure 1 is a side elevation, partly sectional, of a machine constructed according to myinvention. Fig. 2 is an enlarged detail View, partly broken away, of the catch for holding the package-supporting drum at any desired degree of expansion. Fig. 3 is an enlarged vertical section of said drum on the line 3 3 of Fig. 1. Fig. 4 is an enlarged vertical section, partly broken away, on the line 4 4 of Fig. 1. Fig. 5 is an enlarged vertical section, partly broken away, on the line 5 5 of Fig. 1. Fig. 6 is a perspective view of the top of the anvil and stop 60. v

The package-supporting drum consists of a pair of spiders 1, rigidly mounted on the shaft 2, and the segments 6, supported by arms 7, which are vertically slidable in their respective arms of thespider. End pieces 8 are rigid on'the segments. Springs 9 are secured to the end pieces at 10 and to the rings 11, which hang free from the other parts, being supported by said springs. Said springs urge the segments 6 in wardly, and thus normally collapse the drum. The levers 12 are pivoted at 13 to the arms 14, which are rigid on the shaft 2. The ends of said levers 12 rest under the end pieces 8 in the grooved blocks 15, which are rigid on said end pieces. The cones 16 and collar 17 are longitudinally slidable on the shaft 2 and are secured to gether by the arms 18. The spring 19 is se= cured to one of said cones and to one of the spiders 1 and normally urges said cones toward the right of Fig. 1. The collar 20 is loose on the shaft 2 and has the projection 21 abutting the projection 22 on the collar 17. The member 23 is rigidly secured to the bearing-plate 24, in which the shaft2 is journaled. The collar 20 and the member 23 are cut oppositely to form the cam-faces at 25 and the shoulders or stops at 26. A chain or belt 27 is secured to the collar 20 at 28 and connects, through the rod 29, with the crank-arm 30 on the rock-shaft 31. The spring 32 is secured to the frame at 33 and normally raises the arm 29. A foot-lever 34 is rigid on the rockshaft and projects forward of same. Said lever is shown in dotted lines in Fig. 4. The rod 35 rests on the foot-lever 34 and extends upwardly through the guides 36 on the anvil 37. The lever 38 is pivoted to the upper guide 36 and has a perforation 39, through which the rod 35 extends. mally urges the lever 38 upwardly, causing the rod 35 to bind in the perforation 39. The spring 59 urges the rod 35 normally downward against the lever 34.

The rock-shaft 41 is provided with the forwardly-project-ing' foot-lever 42 and the crankarm 43 rigid thereon. The rod 44 is secured to the crank-arm 43 and to the crank-arm 45. The latter is loosely supported on the shaft 2 and has a pawl 46, normally urged by the spring 47 into engagement with the ratchetwheel 48, which is rigid on the shaft 2. The shaft 2 and drum carried thereby may 'be turned through the action of said ratchetwheel and its connection with the foot-lever 42. p The bearing-plate 24 is bolted through the slots 49 in the frame and is vertically adj ustalole therein by meansof the screw 50.

The plates 8 of the drum are connected by arms 51,wl1ich project forward slightly, forming stops against which the hoops are placed in inserting same in the veneer package 52.

The spring 40 nor- A hoop 53 is shown by dotted lines in Fig. 1.

Rods 54 are rigid on the plate 8. (Shown at the right of the drum in Fig. 1.) Stops 55 are slidable longitudinally of said rods and fixed xoo in position by means of the set-screws 56. The stops 55 fix the position of one end of the veneer package. The package shown is provided with outer hoops 57.

The stop 60 is seated in a horizontal perforation passing through the anvil. Said stop consists of a rod bent over at its outer or front end, so that said end projects inwardly over the surface 58 of the anvil. The spring 61 normally urges the stop inwardly, but permits the stop to be pulled outwardly and turned down, as shown by the dotted lines in Fig. 1. The end 62 of the stop serves to fix the position of the package, the latter being placed so that its front end abuts the stop. This stop can be turned down out of the way when a lot of packages of uniform length are handled, the stop 55 having been previously adjusted to fix the position of the package.

The anvil 37 has its upper surface 58 of concave form to fit the outside of the veneer package.

The operation of the device is as follows: The bearing-plate 24 will be adjusted by the screw so that when the drum is expanded and a package is mounted thereon the latter will rest upon the top 58 of the anvil 37. In Fig. 1 the device is shown in proper position for receiving the package, the drum being collapsed. The package is then put on the drum in the position shown. The operator will now step upon the lever 34, thus through the rock-shaft 31 turning the collar 20 and through its cam-faces 25 forcing same toward the left of Fig. 1. Said collar coming against the part 22 of the collar 17 will force the cones toward the left against the levers 12. This will raise the ends of the levers which are under theplates S, and thus expand the drum, urging the segments 6 against the walls of the package. During the operation of expanding the drum the operator will depress the lever 38 so as to permit the rod 35 to drop with the lever 3 1. When the rock-shaft 31 has been turned as desired to efiect theproper expansion of the drum, the operator will release the lever 38. This will bind the rod 35, and thus through the pressure of the rod 35 upon the lever 34 will lock the drum at the desired degree of expansion. The spring 59 is secured to said rod and to the projection 36 and urges the rod normally downward. The strip from which the lining-hoop is to be formed is now inserted in the end of the package against the ends of the members 51, as shown by the dotted lines 53. The operator now nails the hoop to the package at the lowest part, being the part resting upon the anvil 37. The operator then depresses the footlever 42, so as to turn the package slightly through the action of the ratchet-wheel 4:8. The operator will then nail the hoop at the lowest part, continuing to turn the package until the hoop is nailed throughout its length. When packages of smaller diameter are to be handled, the bearing-plate 24 will be lowered slightly by means of the screw 50. For handling short packages the stops will be set toward the left of Fig. 1 on the rods 54. For long packages said stops will be set toward the right. When a lot of packages of uniform length are handled, the stops 55 will be used in preference to the stop 60, but when the packages vary in length the stop is preferably used. This will provide for having the lining-hoops of uniform distance from the adjacent end of such packages. After the hoop is nailed in position the operator merely depresses the lever 38, and thus through the release of the lever 34 and the rock-shaft 31 permits the collar 20 to return to the position shown in Fig. 1, thus permitting the cones 16 to be drawn back to their normal position. The springs 9 will now operate to collapse the drum, from which the package may then be readily removed.

It will be understood that the details of the device shown may be altered in numerous ways without departing from the spirit of my invention. I therefore do not confine myself to such details, except as hereinafter limited in the claims.

What I claim as my invention, and desire to secure by Letters Patent, is-
